How can I board insulated loft?

[Gary111]

My loft is covered with 1 roll thickness of insulaton, I can now use boards as stepping stones as my balance isn't good.
I want to add another roll thickness but still be able to use boards to move around safely once every few years to check the condition as it's an old house.

Should I just squash the insulation with boards, it seems like this would affect how well the insulation works.

If you don't wish to board the entire loft for storage, but just wish to have boarded walkways for inspection; you could use a suitably thick PIR insulation board for the walkways and cheaper roll insulation for elsewhere?

If your boards are not secured I would advise you to screw them down even if you are just using them as a walkway. They could slip off the joists and go through the ceiling possibly resulting in injury to yourself and serios damage to the ceiling. I used loft legs to raise the height of my walkway or raise the height using 2x3 blocks screwed to the joists and then the boards screwed to the blocks.
